Based on shallower-layer high resolution 3D seismic data and deep-layer drilling data, the sedimentary architecture model of turbidite channel complexes in deepwater slope area of West African was studied by the research of external morphology, the internal amplitude characteristics of seismic facies, as well as the analysis of coherence cube stratigraphic slices. The results show that the model can be generalized for two types. One is vertical and lateral stacked patterns between channel complexes, and the other is plan and section migration patterns of single channel in the same channel complexes. For different channel complexes, the vertical stacked model includes three types of isolated, superimposed and incised patterns. And the lateral stacked model includes two types of overlapped and separated patterns.
